"This way," said Elsiebede, drawing her mistress from the public street, now beginning to be thronged with laborers returning from their toil, "the alchemist brooks not impertinent intrusion, and we must beware that no officious attendant, nor curious retainer find the place of his abode." Silently and swiftly the two maidens threaded a narrow alley, leading through an unfrequented part of the town, turning and winding among buildings more and more remote from each other, till it terminated on a grassy heath, surrounding a dilapidated mansion. The sun had already set, and Berengaria, never too courageous, began to shudder at the loneliness of the place. With instinctive fear, she clung tremblingly to the arm of her resolute dependent, whispering, "Whither dost thou lead me? There is here no sign of human life. Let us return." But the spirited slave bent the weak will of the mistress to her purpose; and with alternate assurances of safety and incitements to curiosity, led the way to the rear of the ruined pile, where descending a stone stair, she gave three raps upon a low door. The grating of rusty bolts was heard, the door was cautiously opened, and Berengaria felt herself suddenly drawn within the portal. A glare of dazzling light blinded and bewildered her, and a stifling vapor added to her former terror, almost stupefied her senses. The voice of Elsiebede somewhat reassured her, and as her eyes became accustomed to the light, she took a survey of the scene before her. The apartment seemed to have been originally the kitchen of the castle, one end being occupied by a wide, large chimney, now built up except in the centre, where a furnace, covered with crucibles, glowed with the most intense heat. A white screen with a small dark screen before it, nearly concealed one side, of the apartment, while on the other side from three serpent-formed tubes connected through the wall with retorts, gleamed tongues of colored flame. Various gallipots, alembics, horologues, diagrams, and dusty manuscripts were deposited upon shelves in angles of the wall.
